Steel Ray is Korea's most-watched AI feature film

A 90-minute science-fiction feature made end to end with generative AI has become the most-watched AI film ever released in South Korea, and the record is modest: about 5,300 tickets sold.

"Steel Ray" opened in Korean theaters on October 21, 2026. Director Seol Woo-in told the Korean business outlet Edaily on October 31 that the film had drawn roughly 5,300 cumulative moviegoers through October 30, and Edaily calls it the most-watched AI feature released in South Korea to date.

The film follows Yoon Kang, a young man who puts on a combat suit, the Steel Ray, to fight an autonomous robot that has judged humans a threat. It was made without actors and without sets. A team of just over 10 people spent six months generating roughly 13,000 video clips, each about 15 seconds long, and cutting them into a 90-minute film, Seol said. The production budget was under 1 billion won, and generative AI tools alone accounted for 500 million to 600 million won of it, the Korean outlet MK reported from the film's September press event.

Edaily lists the toolset as Seedance, Kling, Higgsfield, Suno and two other generative services. Human performances were added to the voices: Seol and the production team recorded their own dialogue replacement (ADR), combining the AI-generated faces and movements with the breathing and emotional expressions of real people.

What the numbers say

The audience figure comes from the Korean Film Council's integrated network. Edaily reported that Steel Ray had 4,354 cumulative viewers as of October 25, with cumulative revenue of 43.71 million won. After a 10% value-added tax (about 4.37 million won) and a 3% Film Development Fund levy (about 1.31 million won), about 38.03 million won remains. Split evenly between the theater and the investor-distributor, that leaves roughly 19 million won for the distributor's side.

Steel Ray's box office is the largest of the three, and it is still small enough that theatrical revenue alone cannot cover the production. The pattern is the point. Cutting the cost of backgrounds, effects and motion does not buy a story that fills a theater, and the marketing and distribution a theatrical release needs are unaffected by how the footage was made.

Aino Studio chief executive Ham Seul-gi, whose company co-produced the film, said the team's priority was holding a narrative together across 90 minutes, according to the Korean outlet Cineplay. The production could only make about 15 seconds at a time, so it edited 13,000 results into the runtime and discarded many more.

What to watch

Seol is preparing a sequel, "Steel Ray 2," with a target release date next year, and the team plans to develop the film's AI character, Yoon Kang, into a standalone screen actor it can cast in other productions. The first film's job, Ham said, was to prove that AI could sustain a 90-minute runtime at all.

Seol's own account of the limits is blunter. He told Cineplay that the hardest part was the uncertainty of production conditions, because most generative AI tools are overseas services whose updates and credit policies can move a schedule and a budget.

Steel Ray is in Korean theaters now.
